Mounting Apparatus for Pci Card Bracket

1. A mounting apparatus comprising: a chassis comprising a bottom plate; a first fastener secured to the bottom plate, the first fastener defining a through hole and a positioning slot in an inner wall of the through hole; a bracket configured for securing PCI cards, a securing piece located on the bracket and placed on the first fastener, a securing hole defined in the securing piece and aligned with the through hole; and a second fastener comprising a base portion and a blocking portion, the base portion is engaged in the securing hole and the through hole, the securing piece positioned between the blocking portion and the first fastener, and a positioning portion located on the base portion and engaged in the positioning slot; wherein a receiving hole is defined in the base portion and the positioning portion is slidable in the receiving hole.

2. The mounting apparatus of claim 1 , wherein a resilient member is received in the receiving hole, the positioning portion abuts the resilient member, and the resilient member is capable of sliding the positioning portion.

3. The mounting apparatus of claim 1 , wherein a diameter of the blocking portion is greater than that of the securing hole.

4. The mounting apparatus of claim 1 , wherein the first fastener defines a recess in a bottom of the through hole.

5. The mounting apparatus of claim 1 , wherein the first fastener comprises a head portion, a neck portion and a mounting portion, the neck portion is connected between the head portion and the mounting portion, and the through hole is defined in the head portion.

6. The mounting apparatus of claim 5 , wherein a diameter of the neck portion is greater than that of the mounting portion, but less than that of the head portion.

7. The mounting apparatus of claim 5 , wherein a fixing member is secured to the bottom plate, the mounting portion is fixed in the fixing member, and a circuit board is mounted between the head portion and the fixing member.

8. The mounting apparatus of claim 1 , wherein the securing piece is substantially parallel to the bottom plate.

9. The mounting apparatus of claim 8 , wherein the bracket comprises a first sidewall and a second sidewall substantially perpendicular to the first sidewall, the securing piece is located on the first sidewall, and the securing piece is substantially perpendicular to the first sidewall and the second sidewall.

10. A mounting apparatus comprising: a chassis comprising a bottom plate; a first fastener secured to the bottom plate, the first fastener defining a through hole and a positioning slot in an inner wall of the through hole; a bracket configured for securing PCI cards, a securing piece located on the bracket and placed on the first fastener, a securing hole defined in the securing piece and aligned with the through hole; and a second fastener comprising a base portion and a blocking portion, the base portion is engaged in the securing hole and the through hole, the securing piece positioned between the blocking portion and the first fastener, and a positioning portion located on the base portion; wherein the positioning portion is slidable between a first position, where the positioning portion is engaged in the positioning slot for blocking the second fastener from disengaging from the first fastener, and a second position, where the positioning portion is disengaged from the positioning slot for removing the second fastener from the first fastener.

11. The mounting apparatus of claim 10 , wherein a receiving hole is defined in the base portion and the positioning portion is moveable in the receiving hole.

12. The mounting apparatus of claim 11 , wherein a resilient member is received in the receiving hole, and the resilient member is resiliently deformed when the positioning portion is slid from the second position to the first position and comes back to slide the positioning portion from the first position to the second position.

13. The mounting apparatus of claim 10 , wherein a diameter of the blocking portion is greater than that of the securing hole.

14. The mounting apparatus of claim 10 , wherein the first fastener defines a recess in a bottom of the through hole.

15. The mounting apparatus of claim 10 , wherein the first fastener comprises a head portion, a neck portion and a mounting portion, the neck portion is connected between the head portion and the mounting portion, and the through hole is defined in the head portion.

16. The mounting apparatus of claim 15 , wherein a diameter of the neck portion is greater than that of the mounting portion, but less than that of the head portion.

17. The mounting apparatus of claim 15 , wherein a fixing member is secured to the bottom plate, the mounting portion is fixed in the fixing member, and a circuit board is mounted between the head portion and the fixing member.

18. The mounting apparatus of claim 10 , wherein the securing piece is substantially parallel to the bottom plate.

19. The mounting apparatus of claim 18 , wherein the bracket comprises a first sidewall and a second sidewall substantially perpendicular to the first sidewall, the securing piece is located on the first sidewall, and the securing piece is substantially perpendicular to the first sidewall and the second sidewall.
